Me and OH are going out for a few hours at the weekend and I'm going to leave a bottle of breast milk for MIL to feed my DS. I just wondered if anyone ever takes their milk out of the fridge a few hours before needed to let it come to room temperature instead if warming it? I've read all the information about how long milk keeps etc and it seems that it can be kept at room temperature for 6 hours but just wondered if anyone actually does this? I would take it out of fridge before I leave and it would pro baa be used within 4 hours.
